Crystal structure of the tetra­hydro­furan disolvate of a 94:6 solid solution of [N (2),N (6)-bis­(di-tert-butyl­phosphan­yl)pyridine-2,6-di­amine]­dibromido­manganese(II) and its monophosphine oxide analogue

The MnBr(2) complex of N (2),N (6)-bis­(di-tert-butyl­phosphan­yl)pyridine-2,6-di­amine (1·MnBr(2)) co-crystallizes with 5.69% of the monophosphine oxide analogue (1O·MnBr(2)) and two tetra­hydro­furan (THF) mol­ecules, namely [N (2),N (6)-bis­(di-tert-butyl­phosphan­yl)pyridine-2,6-di­amine]­dibromido­manganese(II)–[bis­(di-tert-butyl­phosphan­yl)({6-[(di-tert-butyl­phosphan­yl)amino]­pyridin-2-yl}amino)­phosphine oxide]di­bromido­manganese(II)–tetra­hydro­furan (0.94/0.06/2), [MnBr(2)(C(21)H(41)N(3)P(2))](0.94)[MnBr(2)(C(21)H(41)N(3)OP(2))](0.06)·2C(4)H(8)O. The 1·MnBr(2) and 1O·MnBr(2) complexes are occupationally disordered about general positions. Both complexes feature square-pyramidal coordination of the Mn(II) atoms. They are connected by weak N—H⋯Br hydrogen bonding into chains extending along [001]. The THF mol­ecules are located between the layers formed by these chains. One THF mol­ecule is involved in hydrogen bonding to an amine H atom.
